这个模型典型的操作包括:将一个共享变量复制到一个局部变量中,进行一些特殊的操作,然后尝试使用CAS来修改该共享变量: voidLockFreeQueue::push(Node*newHead){for(;;){// Copy a shared variable (m_Head) to a local.Node*oldHead=m_Head;// Do some speculative work, not yet visible to other thr...
voidLockFreeQueue::push(Node*newHead){for(;;){// Copy a shared variable (m_Head) to a local.Node*oldHead=m_Head;// Do some speculative work, not yet visible to other threads.newHead->next=oldHead;// Next, attempt to publish our changes to the shared variable.// If the shared v...

Lock-free programming is a way of writing thread-safe code such that in the case of contention, the system is guaranteed to advance as a whole. "Wait-free" programming takes this a step further: the code is set up such that each thread can always advance regardless of what the other is...
However, providing this guarantee comes with a cost: each access to the data structure is slightly slower, as it has to take care of the additional book-keeping necessary.Some data structures provide "nearly wait-free" accesses: the code is wait free unless a thread i...
Apache Storm - Apache Storm is a free and open source distributed realtime computation system. Storm makes it easy to reliably process unbounded streams of data, doing for realtime processing what Hadoop did for batch processing. Storm is simple, can be used with any programming language, and ...
We implemented our analysis and evaluated it on 18 libraries comprising 1245 kLOC. We verifi ed 13 libraries to be free from deadlock, and found 14 distinct deadlocks in 3 libraries. (在新选项卡中打开) 论文与出版物 研究领域 Technology for emerging markets ...
